API for React Native PDF viewer

Apryse React Native now has support for TypeScript. Since not all customers use the language, the typings used in this document will be described using normal JavaScript types. For TypeScript users, type information is automatically provided while coding. They can also be found in our TypeScript source files.

RNPdftron contains static methods for global library initialization, configuration, and utility methods.

Initializes Apryse SDK with your Apryse commercial license key. You can run Apryse in demo mode by passing an empty string.

Parameters:

ScriptRNPdftron.initialize('your_license_key');

Enables JavaScript for Apryse SDK, by default it is enabled.

Parameters:

ScriptRNPdftron.enableJavaScript(true);

Gets the current PDFNet version.

Returns a Promise.

Promise Parameters:

1RNPdftron.getVersion().then((version) => {
2  console.log("Current PDFNet version:", version);

Promise Parameters:

1RNPdftron.getPlatformVersion().then((platformVersion) => {

Note: to add the image file to your application, please follow the steps below:

1. Android

Add the image resource to the drawable directory in example/android/app/src/main/res. For details about supported file types and potential compression, check out this guide.

2. Now you can use the image in the viewer. For example, if you add button_close.png to drawable, you could use 'button_close' in leadingNavButtonIcon.

iOS

1. After pods has been installed, open the .xcworkspace file for this application in Xcode (in this case, it's example.xcworkspace), and navigate through the list below. This would allow you to add resources, in this case, an image, to your project.

• "Project navigator"
• "example" (or the app name)
• "Build Phases"
• "Copy Bundle Resources"
• "+".

2. Now you can use the image in the viewer. For example, if you add button_open.png to the bundle, you could use 'button_open.png' in leadingNavButtonIcon.
